Abstract:
To propose a display device that can make a presenter timely aware of an elapsed time of a presentation.A display device including: a timing unit configured to time an elapsed time from a starting time point; a display control unit configured to control a display of a displayed image and an information image including a display related to the elapsed time; and a time setting unit configured to set a presentation time. The display control unit exerts control such that the display of the information image is displayed over the presentation time, and changes a mode of the information image whenever an elapsed time timed by the timing unit reaches a set time.
Abstract:
[Object] To provide a projector-type display apparatus with ease of maintenance.[Solving Means] According to the present technology, a projector-type display apparatus includes an optical-system-for-projecting, a housing, a fan, an air-filter, and a filter-cover. The housing includes an air-inlet-port, and houses the optical-system-for-projecting. The fan is housed in the housing, air from the air-inlet-port flowing into the fan. The air-filter is attachable to and detachable from the housing, and covers the air-inlet-port. The filter-cover is attachable to and detachable from the air-filter.
Abstract:
[Object] To provide an information processing apparatus, control method, program, and storage medium capable of intuitively performing an operation input to an object within a projection image by moving a laser pointer.[Solution] There is provided an information processing apparatus including: a recognition unit which recognizes an irradiation position of laser light by a laser pointer to a projection image; an acquisition unit which acquires movement information of the laser pointer; and an output unit which outputs a control signal for causing display of an object within a projection image corresponding to the irradiation position to be changed in accordance with the movement information.
